i installed the header which comes with an extension pipe that connects to the cat. you can notice a difference and it made the exhaust note deeper. i have a full 2 1/2" exhaust with a test pipe, no resonator, and a muffler. although, you have to make some modifications the new O2 sensor mounting place because i'm having gas mileage problems but as soon as i fix it i'll let you know and tell you how it's working
how often do they check for emissions? i live in Illinois
